A system for connecting trailer towing components may have a pin having a first leg and a second leg. The system may also have a torsion bar having a first set of splines, and a main beam for a trailer. The main beam may have an insert adapted to selectively receive the torsion bar therein. The main beam may also have at least one guide aperture adapted to selectively receive one of the pin legs. The system may also have a secondary beam adapted to be selectively located at least partially within the main beam. The secondary beam may have apertures adapted to receive at least one of the legs of the pin and the torsion bar.

The present invention provides an improved trailer tongue hinge device that is far superior to prior art trailer tongue hinges. The inventive trailer tongue hinge device is comprised of two identical parts, i.e., units, which impart an equal load on either side of the hinge device as well as five shear points and wear locations that spreads out stress and wear on the hinge device, rather than two shear points and wear locations encountered in the prior art. Further, the improved trailer tongue hinge device is manufactured from mild steel that is capable of bending long before it might break, which makes the inventive hinge device about three times stronger than prior hinges, thus imparting a much longer lifetime and safety profile compared to prior art hinges.

A trailer dolly can include various features to be adjustable between a manual configuration and a vehicular towing configuration. In the manual configuration, a user can manually maneuver the trailer dolly to position the trailer, such as by using one or more retractable handles. Where the user desires to maneuver the trailer with a vehicle, the trailer dolly can be adjusted to the vehicle towing configuration. In an example, the trailer dolly can be coupled to the vehicle with a second hitch attached to the trailer dolly, the second hitch located distally along the tow bar with respect to the trailer hitch supporting the trailer load. Accordingly, the trailer dolly can be used for both manual and vehicular applications and the user can transition between the manual and vehicular configurations while the trailer is hitched to the trailer dolly.

A ball mount apparatus, for hitching a trailer to a vehicle, which can include up to three or more hitch balls of different size connected to a ball block which can be locked, unlocked, and rotated manually, without the use of tools, for positioning a selected ball for use. The ball block can also be rotated by hand between a rearwardly extending towing position and a forwardly extending stowed position.

A grain cart and foldable auger assembly having an upper auger assembly portion with a discharge portion, a lower auger assembly portion with an intake portion, and a joint that allows the upper auger assembly portion to be moved between operating and transport positions. When in an operating position, the upper auger portion and the lower auger portion are offset from each other by an operating offset angle. The grain cart also has a hitch for allowing the grain cart to be towed. The discharge portion is forward of the hitch when in the operating position. Embodiments of the present invention provide, for example, increased forward and side reach, additional storage capacity of the hopper, increased discharge rate from the hopper, and a more compact transport position.

A trailer device for an agricultural vehicle includes a frame part and a guide part longitudinally, displaceably mounted in the frame part. The guide part includes a coupling element provided on an end face. The frame part is pivoted by a lifting apparatus for raising and lowering the coupling element relative to a base frame for attaching to a load-bearing vehicle structure. The device includes at least one spring element arranged between the base frame and the frame part such that the spring element exerts a pretensioning force on the frame part for assisting the raising of the coupling element.
